A group of researchers has created a liquid solar energy storage system that can create electricity on demand. The system can store solar energy for up to 18 years, allowing them to release it when ...

Negative pressure is a rare and challenging-to-detect phenomenon in physics. Using liquid-filled optical fibers and sound waves, researchers have now discovered a new method to measure it. In ...

Liquid foams have a remarkable property: they completely block the transmission of sound over a wide range of frequencies. Physicists have studied how sound is attenuated in liquid foams. Their ...

Save your breath: A new way to make bubbles requires only sound waves. Scientists made the bubbles in levitated drops of liquid, held aloft with sound waves. Tweaking the sound waves caused the ...

Reporting in The Journal of Physical Chemistry B, researchers were surprised to find that different frequencies of sound produced different patterns in a color-changing liquid. Studying reactions like ...

Streams of sound are now all you need to make objects dance in the air and combine. A levitation device is the first to use high-frequency sound waves to bring together floating particles and liquid ...
